Engel elements in groups of automorphisms of rooted trees (Marialaura Noce, University of Bath)

28.04.2020 16:30

Groups of automorphisms of (d-adic) rooted trees have been studied for years as an important source of groups with interesting properties. For instance, the (first) Grigorchuk group is an example of a group where the set of left Engel elements is not a subgroup. In this talk we survey recent results about Engel conditions in some general families of groups of automorphisms of rooted trees.
